The comment about the lack of culture coming out of Russia and the suggestion that whatever you had in mind would be antithetical to “an open and free Internet” makes it look to me like you were proposing that Russia somehow being completely disconnected from the net would be no great loss. If that’s not what you were proposing, what on earth did you mean?
Then enlighten me! Explain to me this great societal benefit we get from leaving them on the 'net. Because it sure seems 90% of what’s coming out of Russia is: hacked infrastructure, spreading disinformation, sowing discord and tilting our elections. I understand that it’s unfair to the Russian people, but at what point do we stop drinking the poison that is being dished out by their government? We shouldn’t all be a victim to their government’s motivations.
If you cut off russia from the internet, you will gain nothing. Because the FSB is clever enough to operate in other countries. Go to poland. Get a few SIM cards. Start a company in Kenia as a front and use it to funnel hacker into the internet. Rent a flat in Germany and get a landline. Ukraine already raided russian desinformation centers in their own country - they just did rent a flat and brought a few hundred phones with them.
